Abstract

1.
One per cent eosin and 1 per cent methylene blue mixtures in talcum powder and corn starch were used to stain the mosquitoes.

2.
Ninety-five per cent of mosquitoes captured were Anopheles quadrimaculatus.

3.
Daily catches are inadequate to indicate the extent of anopheles turnover.

4.
The maximum flight noted was 0.4 mile. The maximum interval of time after which stained mosquitoes were recaptured was nine days.

5.
In all, 616 mosquitoes were stained; 5541 mosquitoes were later caught, 3.7 per cent of those stained were recaptured, but only 1.9 per cent of those stained were recaptured in the place where they had been stained.
